DSC 3G-3G A	3G-SDI to 3G-SDI Scaler	60-1453-01	Retired

This product has been retired.

The Extron DSC 3G‑3G A is a high performance 3G‑SDI scaler that converts between 3G‑SDI, HD‑SDI, and SDI resolutions and frame rates. It accepts, scales, and outputs SMPTE video resolutions from 480i and 576i up to 1080p/60 and 2K. The DSC 3G‑3G A features advanced Extron video signal processing with deinterlacing of signals up to 1080i, and Deep Color processing. The DSC 3G‑3G A also provides flexible audio capability with analog audio embedding, de‑embedding, and level adjustments. Dual SDI outputs, genlock, and an input loop‑through facilitate integration in demanding professional environments, while the compact enclosure simplifies installation. The DSC 3G‑3G A is ideal for applications with professional video systems, including video editing and production, rental and staging, medical imaging, and large‑scale presentations.

High Performance Video Processing

The DSC 3G‑3G A provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for content sources originating from film. In addition, the DSC 3G‑3G A provides two simultaneous 3G‑SDI/HD‑SDI/SDI outputs so that two displays can be driven simultaneously, without the need for additional equipment.

To enhance and simplify integration, the DSC 3G‑3G A offers automatic input cable equalization and reclocking on the buffered SDI loop‑through. Input equalization restores and reshapes incoming 3G‑SDI signals, reducing the need for additional signal conditioning equipment by compensating for weak source signals or signal loss from a long input cable.

Selectable FILL and FOLLOW modes are also available to ensure the proper aspect ratio of the output. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Enhanced Audio Capabilities

The DSC 3G‑3G A offers enhanced audio management capabilities, including SDI audio embedding and de-embedding, input gain and attenuation controls, input audio muting, and output volume control. To suit the needs of the application, convenient analog two channel audio input and output connections are provided for embedding audio onto the SDI output, and sending de‑embedded content to a sound system or other audio destination. The output can be set for stereo or dual mono. The DSC 3G‑3G A provides gain and attenuation adjustments for the analog stereo input, as well as the ability to mute the analog stereo or SDI audio input.

Multiple Options for Control and Operation

The DSC 3G‑3G A features front panel controls for quick access to functions. Remote configuration and control are available via RS‑232 and USB. The on-screen menus provide control over the unit's functions and settings, including quick access to key parameters such as input and output video formats and resolutions. Additionally, LED indicators on the front panel provide visual confirmation of input and output signal format, and signal presence. The DSC 3G‑3G A is housed in a 1U, half rack width metal enclosure and can be easily integrated into a variety of environments.

Features

3G‑SDI video cross conversion — The DSC 3G‑3G A provides high quality scaling and conversion of 3G‑SDI, HD‑SDI, and SDI video resolutions and frame rates, with audio embedding and de‑embedding.

Inputs: One 3G‑SDI/HD‑SDI/SDI with buffered input loop‑through on BNC connectors, balanced/unbalanced stereo audio on 5‑pole captive screw

Outputs: Dual 3G‑SDI/HD‑SDI/SDI on BNC connectors, balanced/unbalanced stereo audio on 5‑pole captive screw

Accepts 3G‑SDI/HD‑SDI/SDI signals up to 2.97 Gbps — The DSC 3G‑3G A accepts video formats from 480i and 576i to 1080p/60 and 2K. It complies with SMPTE 259M, 292M, 424M, and ITU digital video standards.

Two simultaneous 3G‑SDI/HD‑SDI/SDI outputs — Simultaneous 3G‑SDI/HD‑SDI/SDI outputs are available for driving two displays.

Advanced scaling engine with 30‑bit precision processing and motion-adaptive deinterlacing for signals up to 1080i — Image scaling and video format conversion are performed at 30‑bit precision for enhanced color accuracy and picture detail. Advanced deinterlacing for all interlaced signals up to 1080i delivers optimized image quality.

SDI audio embedding — Analog stereo audio can be embedded onto the SDI outputs.

SDI audio de‑embedding — Any pair of AES audio channels from the SDI input can be extracted to the analog output. Alternatively, any pair of AES audio channels, or all AES audio channels can be passed to the SDI outputs.

Selectable output rates from 480i and 576i to 1080p/60 and 2K — Available output rates include 480i, 576i, rates up to 1080p/60, and 2K.

Input equalization and reclocking on buffered loop‑through — Automatically equalizes incoming 3G‑SDI signals, and reshapes and restores signals on the buffered loop‑through.

Aspect ratio control — The aspect ratio of the video output can be controlled by selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which preserves the original aspect ratio of the input signal.

Genlock input with loop‑through — Allows for synchronization to an external reference signal and supports bi‑level or tri‑level sync for integration into broadcast and production applications.

AFL™ - Accu‑RATE Frame Lock — A patented technology exclusive to Extron that locks the output frame rate to the input to eliminate stuttering caused by frame rate conversion.

Front panel LED indicators for signal format, presence, and power — Provides visual indication of system status for real-time feedback and monitoring of key performance parameters.

Image freeze control — A live image can be frozen using RS‑232 serial control or USB.

Auto Input Memory — When activated, the unit automatically stores size, position, and picture settings based on the incoming signal. When the same signal is detected again, these image settings are automatically recalled from memory.

On‑screen menus — Intuitive on‑screen menus allow for easy system setup using the front panel controls. Key parameters such as input and output video formats are conveniently grouped on the initial Quick Setup screen, while additional screens provide full control over the unit's other functions and settings.

Output Standby Mode — The unit can be set to automatically mute video and sync output to the display device when no active input signal is detected. This allows the projector or flat-panel display to automatically enter into standby mode to save energy and enhance lamp or panel life.

Power Save Mode — The unit can be placed in a low power standby state to conserve energy when not in use.

Automatic 3:2 and 2:2 pulldown detection — Advanced film mode processing techniques that help maximize image quality for NTSC, PAL, and 1080i sources that originated from film.

Picture controls for brightness, contrast, and detail, as well as horizontal and vertical positioning, overscan, and sizing

User presets — Memory presets are available for each input to store and recall optimized image settings.

Internal video test patterns and pink noise generator for calibration and setup — The unit offers several video test patterns and audio pink noise to facilitate proper system setup and calibration of display devices.

Audio input gain and attenuation — Gain and attenuation can be adjusted for the analog stereo input.

Integrated audio delay — The audio output is automatically delayed to compensate for latency introduced by the video processing.

Input audio muting — The analog stereo or SDI audio input can be individually muted.

Output volume control — Provides master volume control for the analog line level output.

Front panel security lockout — This feature locks out all front panel functions; all functions however, are available through USB or RS‑232 control.

RS‑232 control port — Enables the use of serial commands for integration into a control system. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII commands that allow for quick and easy programming.

Front panel USB configuration port — Enables easy configuration without having to access the rear panel.

Easy setup and commissioning with Extron's PCS - Product Configuration Software — Conveniently configure multiple products using a single software application.
